The hybrid car drive train technology utilized in vehicles bearing the Toyota and Lexus marques is referred to by Toyota Motor Corporation as Hybrid Synergy Drive (HSD), also known as Toyota Hybrid System II. The technology was first made available on the Prius and has since been modified for the plug-in hybrid Prius as well as the electric drive system of the hydrogen-powered Mirai. It is also available as an option on a number of other Toyota and Lexus vehicles. Toyota previously granted Nissan a license to use its HSD technology in the Nissan Altima Hybrid. Other automakers can purchase hybrid transmissions from its components supplier, Aisin Seiki Co.
Unlike the majority of other brand hybrids, which cannot and are categorized as mild hybrids, HSD technology creates full hybrid vehicles that can run on the electric motor alone. A planetary gearset and an electric drive are also combined in the HSD, which functions similarly to a continuously variable gearbox. With a drive-by-wire technology like the Synergy Drive, there is no physical link between the engine and the engine controls; instead, an HSD car’s accelerator and gearshift only send electronic signals to a control computer.
The original Toyota Hybrid System (THS), which was utilized in the Toyota Prius from 1997 to 2003, has been improved with HSD. In 2004, a revised Prius was equipped with the second generation technology for the first time. The system was introduced in the 2006 Camry and Highlander and would eventually be introduced in the 2010 “third generation” Prius and the 2012 Prius c. The name was changed in anticipation of its use in vehicles outside the Toyota brand (Lexus; the HSD-derived systems used in Lexus vehicles have been dubbed Lexus Hybrid Drive). With the ICE/MG1 and MG2 having separate reduction paths and being combined in a “compound” gear that is connected to the final reduction gear train and differential, the Toyota Hybrid System was introduced on all-wheel drive and rear-wheel drive Lexus models. It is designed for increased power and efficiency as well as improved “scalability” (adaptability to larger as well as smaller vehicles). [2] [3] Toyota sold one million hybrids globally by May 2007, two million by the end of August 2009, and five million by March 2013. [4] [5] More than 7 million hybrid Lexus and Toyota vehicles had been sold globally as of September 2014[update]. [6] As of March 2013[update], 38% of TMC’s global hybrid sales were made in the United States. [5]

What is the operation of the Toyota Hybrid Synergy drive?
The genuinely brilliant part is right here. Energy can truly be recycled using this method. How? In any case, when you drive, you produce energy. braking is a good example. Most autos entirely waste that energy. However, the Auris HSD allows it to store the energy and use it once more to drive the electric motor.
Two engines power the brand-new Auris HSD. One gasoline and one electric. Together, they provide you with additional power and responsive torque as and when you require it. More specifically, it generates 136hp. However, if you require any additional performance, just hit the Power button and take it easy.
Braking and Deceleration: The technology reuses kinetic energy to replenish the battery.
Both engines are automatically turned off at a standstill to save energy.
It goes without saying that city driving raises the gas prices for most vehicles. The new Auris HSD, however, isn’t like most automobiles. It has two engines and recycles energy, to start. one gasoline. single electric A superb combination to produce 3.8 l/100 km. Additionally, you can lower that figure even more when driving in eco mode.
However, if you want to fully eliminate that number, just switch to electric EV-mode, ease up on the accelerator, and you won’t need a single drop of fuel when accelerating up to 50 km/h.
Experience the silence by switching the new Auris HSD to electric EV-mode. You have to see it for yourself to believe it. The zero-emissions electric EV mode also offers a luxurious ride. It’s actually a pretty peaceful place to be.
Because an electric motor and a gasoline engine work in harmony, the new Auris HSD emits only 87g of CO2 per kilometer. Really amazing for a family vehicle.
In fact, it can go from 0 to 50 km/h in electric EV mode while emitting zero emissions. In a balloon, you would essentially find more CO2.
Is a CVT a Hybrid Synergy Drive?
Engines in Hybrid Synergy Drive use ‘Drive by Wire’ technology. The engine and accelerator paddle are not physically connected in this technique. Drive by wire is entirely managed by the ECU and a slew of electrical sensors. The throttle position sensor also establishes how much power the engine needs to operate at a particular throttle response.
The majority of conventional engines don’t operate at their best efficiency. As a result, the engine wastes valuable fuel and torque. Even the makers only have a few tools to use in these situations. However, in the case of the Hybrid Synergy Drive, the computer or the e-CVT (electronic continuously variable transmission) chooses the best gear ratio at any given moment. As a result, the engine operates at its best RPM, increasing efficiency. When not needed, this mechanism can also turn off the IC engine.
Wheel speed and engine coordination are kept in good working order by hybrid synergy drive. It makes an effort to maintain steady engine RPMs between 1500 and 2000, the range where IC engines are supposedly at their most effective.
Which Toyota hybrid model is the best?
The Toyota Prius Prime is the company’s most energy-efficient hybrid vehicle to date. It is rated with amazing 133 MPGe* and an EPA-estimated combined fuel economy value of 54 MPG. Drivers may travel up to 25 miles on electric power alone.
How does the hybrid system in a Toyota work?
The car’s electric drive motor is its only source of power when it is beginning, halted at stop signs and intersections, or driving slowly. It obtains its electricity from the hybrid battery by way of the power control unit. In addition to saving on gasoline and producing no emissions, the electric drive motor aids in acceleration by instantaneously delivering the maximum torque. Think of it as a win-win scenario.
The engine and electric drive motor work together to produce power for smooth and forceful acceleration when the car has to accelerate quickly, such as when trying to pass another vehicle on the highway. The hybrid battery contributes by supplying the additional energy required to boost the drive power. When you need it most, the Electronically Controlled Continuously Variable Transmission (ECVT) and the mix of direct mechanical power from the engine and electric power from the motor give quick acceleration.
The gasoline engine and electric motor both provide power to the wheels when cruising and under typical driving circumstances. At faster speeds, the electric drive motor takes over as necessary, but at slower speeds, it works the other way around. With the help of the planetary gear, engine power is split between the wheels and the generator for maximum efficiency. In addition to powering the electric motor, the generator also aids in recharging the hybrid battery. It all functions flawlessly in concert to provide outstanding outcomes, which is why it is dubbed a hybrid synergy drive system.
Most cars lose energy when they brake because of heat and friction. But with a Toyota hybrid vehicle, using the accelerator or using the brakes actually aids in battery recharging and increases system effectiveness. Regenerative braking allows for the conversion of kinetic energy from the wheels into electricity, which is then transmitted by the electric motor to the power control unit and stored in the hybrid battery. In other words, the car’s wheels act as a generator, powering the electric motor. Particularly useful in stop-and-go urban driving, this system. The idea of reusable energy is a novel one.
Under normal conditions, just the electric drive motor will be working when you put a hybrid automobile into reverse. This is due to the power control unit turning off the gasoline engine when it is not required, such as when coasting or traveling at a low pace. In fact, the gasoline engine will only start while the vehicle is moving in reverse to charge the hybrid battery.
How quickly does a hybrid transition to gas?
A Prius often shifts from battery to petrol while traveling at speeds of at least 15 mph. Call the hybrid experts at Luscious Garage in San Francisco, California, at 415-213-2336 for all your hybrid vehicle repair needs right away!
Do Toyota hybrids have high maintenance costs?
An overall hybrid car may require less regular maintenance. Low speed driving causes the gas engine to cut down and the electric motor to take over. This results in significantly less deterioration of your gas engine. Even less frequently than on a typical car, oil changes are not required. This is because, as opposed to the typical 3,000 miles for an all-gas car, the majority of hybrid vehicle manufacturers advise waiting until you reach 5,000 miles between oil changes. Due to the hybrid’s usage of a less-heated regenerative braking system, your brakes may last longer as well. The brakes themselves and your brake pads ought to last longer.
In general, maintaining a hybrid car shouldn’t be all that expensive compared to a regular car. Your hybrid will pay you back with less stress and lower out-of-pocket costs thanks to a variety of advantages, such as higher gas mileage and reduced wear and tear.
